Time-to-Digital Converters (TDCs) are essential components in high-precision digital systems for accurately measuring short time intervals between events. This project presents the design and implementation of a two-level TDC architecture that com bines both coarse and fine time measurement techniques to achieve improved resolution and dynamic range. The coarse measurement is implemented using a counter-based TDC that counts clock cycles between start and stop signals, offering simplicity and a wide measurement range but limited resolution. To overcome this limitation, a fine measurement stage is introduced using a buffer delay line, which subdivides a single clock period into smaller intervals based on known logic gate delays. By integrating both methods, the proposed TDC achieves a balance between high timing resolution and broad range, making it suitable for applications such as time-of-flight measurements, digital communication systems, and precision instrumentation. This report outlines the design methodology, simulation results, and performance evaluation focusing on resolution, linearity, and timing accuracy.
